% DDOT Given N x m matrix X, creates (blkstart(end)-blkstart(1)) x m matrix
%   ddotX, having entries d[i]'* xj[i] for each (Lorentz norm bound) block
%   blkstart(i):blkstart(i+1)-1. If X is sparse, then Xblkjc(:,2:3) should
%   point to first and 1-beyond-last nonzero in blkstart range for each column.
